Adaptive coding and modulation using Reed Solomon codes for Rayleigh fading channels

Abstract

An adaptive forward error control and modulation scheme is proposed for slow Rayleigh fading channels. The adaptive scheme employs a family of RS codes of different rates and multiple phase shift keying (MPSK) modulation schemes according to the states of the channel. This uses a channel estimator to select the most appropriate codulation (coded-modulation) scheme. Simulation results show that the adaptive scheme gives significant improvement in the BER and throughput performance.
